P2i shows off nanotech coating that protects your smartphone's delicate innards from the invasive evil of water

InfoWorld|Feb 27, 2014

Smartphone are technological marvels, but as soon as a bit of liquid gets inside them, it's game over, man. Now, at Mobile World Congress, a company called P2i showed off a new nanotechnology that could save your smartphone from a dreaded watery death.

The real problem with moisture in smartphones is that it creates a short circuit, rendering the phone useless. But if P2i applies its nanotechnology coating to a smartphone's electronics, it creates a waterproof barrier. That is, if water enters the device, it won't get a chance to perform its short-circuity evil because it will never actually come in contact with the circuitry. The video above shows phones being soaked in a shower for 20 minutes and functioning just fine. You'll never have to suffer from angst due to rain, puddles, and, yes, toilets, again -- at least not as far as your smartphone is concerned.
